部分因子实验设计结果表明葡萄糖、硫酸铵、硫酸镁及磷酸氢二钾为影响Saccharomyces cerevisiae B5产生高选择性羰基还原酶的四个显著性因素。

To investigate the expression, location and function, long distance PCR was used to expand the targets containing open reading frame. The expressive vectors of prokaryotic and eukaryotic cells were constructed after product purification and connecting with vectors. The prokayotic vectors were induced to express the protein by IPTG and the protein was seen by denaturalization PAG electrophoresis and dyeing. The eukayotic expressive vectors were transfected into culture cells and the protein was found in the nulceolus under the observation of the confocal microscope. The transfected cells were chosen by the geneticin (G418). The cell cyele was examined by flow cytometer and the cell numbers were reduced obviously in the stage of G〓-G〓 and G〓-M, but increased distinguishably in the S stage.

为研究磷酸化应激诱导蛋白的表达、定位和功能，采用了长距离聚合酶链反应扩增含有开放阅读框架的靶片段，经产物纯化、与载体连接，分别构建了STIP1基因的原核表达载体和真核表达载体；IPTG诱导原核表达载体，变性聚丙酰胺凝胶电泳与染色后，可见相应大小的蛋白质表达；STIP1基因的真核表达载体转染细胞系后，共聚焦显微镜下观察STIP1蛋白主要分布于细胞核内；用药物筛选STIP1基因转染的细胞后，流式细胞仪检测细胞周期，可见G〓-G〓期和G〓-M期的细胞明显降低，S期细胞明显增多。
